Sort Different sections based on values in a column

Hi all,

I need some help in sorting different sections based on values in a column. I have attached a sample workbook to help show what I am talking about.

So basically each section will have a different amount of lines everytime and they will be numbered differently, so basically I want a macro that can recognize the different sections (regardless of how many rows) and then sort the rows based on the the values in column smallest to largest.

-Thanks!
